; Referring tovthe means for carryingrout the object thus broadlystated,.a' rotary yarn guide 1s mounted upon arevolvmg support above theplane of the needles, together witha' relatively stationary rack orother suitably formed element, whereby said guide, which is normallyfixed with respectto said support, upon encounteringgsaid element isitself rotated independently oi' its support, with the result that fora'relativ ely brief portion of its circular path it describes aplanetary motion, and in so doing carries the yarn i around theupper-portions of as many needles as may be desired, and again remainsfixed until it again encounters said element,

With theforegoing facts in mind, the {ins 'vention comprises furtherdetails of construction and operation such as areclearly brought out inthe following description, when read in conjunction with theaccompanyingdrawings in which Fig, 1 is'a side elevation of oneembodiment of the invention, showing" the rack element inverticalsection; land Fig. 2 is ahorizontal-section on the line of Fig.l.

VVhe'n the attachment is applied to a re volving cam machine, the rackwith teeth I 21 revolves with the cam or cams, and the v cylinder 10,disc 9, yarn rack 2, etc., remain s a ya a There may be'employed asmanyof these improved yarn feed devices as may be desired, or as may bepracticable, depending upon the type and design of machine which may beinvolved. The disc 9 with its sup- Egrting drive shaft 1 and yarn rack 2may rotated'by any suitable mechanism which ,may comprise either thesame or different means thanthat which rotates the cylinder 10. Also,the respective guide tubes 13, and l4-may bewithdrawn and replacedwhen-o ever necessary or desirable, forrepair or substitution by simplylifting them upwardly and free from the bores 12 in the supporting disc9, after firstlooseningthe nuts or screws by which they are operativelysecured in position.

In the operation of the invention, the

knitting machine is operated in the usual manner, but the yarn 6 passesto the needles the yarn from its depending free end needles which'may bein raised position at a predetermined point in the circular needle row,or in the path of the arc of needles as the latter, are being raised andlowered out of their normal, position of rest. 'Through each of-theserotatable yarn feeds can be passed adifferent type of yarn or silkthread, or as manydifi'erent colors as may be desired,

either singly or in multiple, so that as many a; stripes or otherossible designs are produced in the finished tary feeds. a V 7 Havingthus described my invention, what I claim and desire to protect byLetters Patit product as there are roent of the United States is 7 1LThecombination of a knitting'machine comprisinga cylinder of needles anda support rotatablemin synchronism therewith, with a yarn guiderotatably carried by said sup ort upon an'axis eccentric to the axis ofsal support andcomprising a toothed head having aicentralbore and atubecommunieating with said bore and having its free end terminatinglaterally of itsaxisof rotation with respect tosaid support and belowthe level of theupper ends of said needles'when they are in raisedposition, a relatively stationarytoothed rack adapted to engage andro'tate'the toothed head of said guide with respect tosaid supportv andto said needles while in a predetermined portion of its path or orbit,to cause yarn from the free end of said guide tube to encircle apredetermined set of needles, and resilient frictionally braking meansengaging and limiting the rotation of said head with respect to saidsupport to only the movement imparted thereto by said rack.

I 2. The combination of a knitting machine comprising-a cylinder ofneedles and a support rotatable in synchronism therewith, with a yarnguide rotatably carried by said support upon an axis eccentric to theaxis of sa1d support and comprising a head having a central bore and atube communicating with saidbore and having its free end terminatinglaterally of its axis of rotation with respecttos'aid support, means torotate said head of said guide with respect to saidsupport and to saidneedles while in a predetermined portion of its path or orbit, to causeyarn from the free end of said guide tubeto encircle a predetermined:set of needles, and resiliently frictionally braking means engag, ing,and limiting the rotation of said head withrespect to said support toonly'theomovement imparted thereto by said first means.

In testimony whereof I have afiixed my signature.
